How will the wind turbines generate electricity?
Modern wind turbines harness the power in the wind to drive a generator. When the rotor rotates, it drives the generator via a gearbox. The generator produces electricity at 690 volts and 50Hz. This is then transformed within the turbine to 33,000V (33kV). Subsea cables will link the turbines to one or more offshore transformer stations. Two or more subsea cables will then export the power to shore. Onshore infrastructure will include a new sub-station and underground cables or overhead line, depending on the location of the grid connection. The turbines will be fully automated and can be operated remotely. The turbines will produce power in winds from 6mph to 65mph and can withstand gusts of up to 130mph.
